Stop The Engine; Maintenance Schedule - Briggs & Stratton 120000 Operator's Manual

WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result
in burns or death.
When you start the engine
• Make sure that the spark plug, muffler, fuel cap and air cleaner (if equipped)
are correctly installed.
• Do not crank the engine with the spark plug removed.
• If the engine is flooded, set the choke (if equipped) to the OPEN or RUN
position. Move the throttle (if equipped) to the FAST position and crank until the
engine starts.
• If there is natural or LP gas leakage in the area, do not start the engine.
• Because vapors are flammable, do not use pressurized starter fluids.
WARNING
Rotating parts can entangle hands, feet, hair, clothing, or accessories and result
in traumatic amputation or laceration.
• Operate equipment with the guards correctly installed.
• Keep hands and feet away from rotating parts.
• Remove jewelry and make sure that long hair is away from all rotating parts.
• Do not wear loose clothes or items that could become caught.
WARNING
Fast retraction of the starter cord (kickback) will pull your hand and arm to the
engine faster than you can let go. Broken bones, fractures, bruises or sprains
could result.
• To prevent kickback when you start the engine, pull the starter cord slowly until
resistance is felt and then pull quickly.
• Before you start the engine, disconnect or remove all external equipment and
engine loads.
• Make sure that direct-coupled equipment components, such as, but not limited
to, blades, impellers, pulleys, and sprockets, are correctly attached.
Types of Start Systems
Before you start the engine, you must know the type of start system on your engine.
Your engine will have one of these types.
•
®
ReadyStart and 1-Step Start System: These systems have a temperature
controlled automatic choke. It does not have a manual choke or a primer.
• Choke System: This system has a choke to be used in cool temperatures. It
does not have a primer.
To start your engine, follow the instructions for your type of starting system.
NOTE: Your equipment could have remote controls. Refer to the equipment manual for
location and operation of remote controls.

Maintenance
Maintenance Information
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if
mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not
empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted
in a different direction, it will not easily start because of oil or fuel contamination of the air
filter or the spark plug.
WARNING
Accidental engine spark can cause an electric shock, fire or explosion and could
result in entanglement, traumatic amputation or laceration.
Before you make adjustments or repairs:
• Disconnect all spark plug wires and keep them away from the spark plugs.
• Disconnect the battery wire from the negative battery terminal (only engines with
electric start).
• Use only the correct tools.
When you check for spark:
• Use an approved spark plug tester.
• Do not check for spark with the spark plug removed.
WARNING
Replacement parts must be of the same design and installed in the same position as the
original parts. Other parts could result in damage or an injury.
NOTICE
All the components used to build this engine must remain in place for correct operation.
See a Briggs & Stratton Authorized Service Dealer for all maintenance and servicing of
the engine and engine parts.
Emissions Control Service
For maintenance, replacement, or repair of emissions control devices and
systems, contact a qualified off-road engine repair establishment or service
